## Questions & Answers

**Q: hi is this suitable for use on fish ponds and fountains, and what colour does it dry too,?**
A: If it is a fibre glass pond liner then this product can be used to repair it.  However, fastglass will not stick to polythene or polypropylene.  The reinforcing mat is white, the resin is clear and the hardener is red.  This creates a clear slightly pink finish to the resin dependant on amount of hardener used, thickness applied and number of coats, etc., etc..   The white reinforcing mat will probably show through the resin to some degree.  Personally for pond repairs, I prefer to use a similar product which has reinforcing strands incorporated in the resin.  It mixes up into a thicker, more substantial paste that can be applied at virtually any thickness required and is far easier to form into the required contours, etc..  It is also a more neutral colour.  If your pond is currently stocked you will need to ensure that there is nothing in the repair product that will harm the fish, etc., so you may need to seal the repair with a little pond paint.

**Q: What area of glassfibre matting is included in this?**
A: The mat is 10 inches by 42 inches. There is a 500ml Resin and enough hardener for the resin. Two pairs of gloves, two lollypop sticks for mixing, two small containers for mixing resin and a half inch paint brush. I found this a great kit but ran out of resin and hardener before using all the matting.

**Q: Can this product be used to seal a cracked shower tray made from thermoplastics?**
A: Should be OK but you need to slightly rough up the area to be sealed

**Q: hi i have a i slight dent and a hole in the back end of my caravan , is this the correct product to use to repair it , thanks**
A: Depends on how big the hole & what material the dent is in. Vans tend to be aliminum panels but corners can be plastic. Personally I would use a car type filler then cover with a stick on decal. If hole is large use an Aliminium patch. Hope this helps
